AS-1 line typically extends between 4 and 6 inches parallel to the top of your windshield. AS-1 designation line is typically marked by glass manufacturer on the top edge of your windshield.

Depending on vehicle, your AS-1 strip may already be tinted. In most states windshield tint must not have any reflectiveness, and illegal colors typically include blue and red.

Some state tint laws specify exact number of inches you are allowed to tint on front windshields. Other states define this windscreen area simply as an AS-1 line. Learn more about AS-1 Line.

Federal vehicle ID label found on driver's front door frame will tell you whether your vehicle is classified as passenger or multi purpose vehicle.

In most states vehicles fall under these two categories.

An illegal window tint in Michigan is classified as a civil equipment infraction (under MCL 257.709) rather than a moving violation, meaning it results in zero points on your driver’s license.

Fines typically range from $70 to $111 (e.g., around $70–$95 for the basic citation, or roughly $110–$111 total including court and local costs).

Many courts and local agencies will waive or dismiss the fine if you remove the illegal tint (or bring the vehicle into compliance), have the fix signed off by a law officer, and present proof to the court within a specific window (often 10 calendar days).
